Method for producing decorations on an object and resulting object

ABSTRACT

The invention concerns a method for producing decorations on an object by machining a multilayer structure ( 1 ) which consists in machining at various depths a complex consisting of an assembly of materials which are different in particular in shade and/or colour, the multilayer structure ( 1 ) being made up of an arrangement of bars ( 2 ) with polygonal cross-section, and varied shades and/or colours. The method consists in machining said multilayer structure ( 1 ) with one or several turning processes.

BACKGROUND OF THE INVENTION

[0001] (1) Field of the Invention

[0002] The present invention relates to a method for producingdecorations on an object through machining a complex, and an objectobtained through said method.

[0003] (2) Description of the Prior Art

[0004] There are already known methods for producing decorations on anobject through machining a complex formed by assembling differentelements, namely made of wood, which consist, in a first stage, inmanufacturing such complex by performing a superposition of layers ofelements of different shades and/or colors, and eventually of a varyingthickness, then in machining said so obtained complex according tovariable depths, in order to cause variable relief patterns andgeometrical shapes to appear, depending on the layer or layers involvedby the machining and on the way the machining is carried out.

[0005] These methods are however limited as regards the decorationeffects achieved. They are namely aimed at manufacturing walls, wherevariable concentric shapes are achieved through varying the machiningdepth; such a method is disclosed, for example, in FR 2,700,500.

[0006] DE 31 42 446 also provides a similar method; in addition, itprovides a process consisting in sculpting a cylindrical blockcomprising concentric layers.

[0007] From U.S. Pat. No. 1,994,204 is also known a method for producingmosaics, consisting in manufacturing a block through assembling barshaving a rectangular cross-section, then in cutting said block accordingto a plane non-parallel to those in which said bars are assembled.

SUMMARY OF THE INVENTION

[0008] The object of the present invention is to provide a method forproducing decorations on an object through machining a complex of thetype as above-mentioned, and which allows achieving decoration effectsof a novel type.

[0009] The method for producing decorations on an object throughmachining a complex is of the type consisting in carrying out themachining at variable depths of a complex consisting of an assembly ofmaterials that differ from each other namely as regards their shadeand/or their color, said complex consisting of an arrangement of barshaving a polygonal cross-section and variable shades and/or colors, andit is characterized in that it consists in machining said complex bymeans of one or several turning operations.

[0010] Turning allows achieving highly variable, but homogenous and alsosymmetric patterns when the complex is properly centered during theturning operation. Less uniform shapes can however be created by causingsaid complex to be off-center.

[0011] According to an additional feature of the process according tothe invention, the complex consists of an assembly of bars made of woodof variable species.

[0012] By using different and variable species, thus of different shadesand even colors, and by assembling them at random or by arranging themin an accurate way, carrying out the turning allows achieving particulargeometrical shapes.

[0013] According to another additional feature of the process accordingto the invention, the complex consists of an assembly of bars made outof one or several plastic materials.

[0014] The plastic material or materials are used namely for thecountless possibilities of varying their colors.

[0015] According to another additional feature of the process accordingto the invention, the complex consists of an assembly of bars made outof materials of various kinds.

[0016] It is possible to manufacture a complex from different materialswhile complying with determined criteria, in order to avoid namely adeterioration of the assembly in the course of time, for example due todifferent coefficients of expansion. Furthermore, one should avoidmixing hard materials with soft materials, such an assembly being likelynot to be capable of being machined in a satisfactorily way.

[0017] It should be noted that an interesting esthetical result isachieved by mixing transparent plastic materials with opaque materialssuch as for example wood.

[0018] According to another additional feature of the process accordingto the invention, the complex consists of an assembly of bars ofdifferent transversal dimensions.

[0019] It is possibly to vary the transversal dimensions of the bars,provided however that they are arranged without leaving any gap.

[0020] According to another additional feature of the process accordingto the invention, the complex consists of an assembly of bars ofdifferent polygonal cross-sections.

[0021] The bars do not compulsorily have the same polygonalcross-section, such as a square, rectangular, triangular, hexagonalcross-section; by way of an example, a complex may thus be formed by thearrangement of bars with a square and rectangular cross-section, or withan octagonal and square cross-section.

[0022] The advantages and the features of the process according to theinvention will clearly appear from the following description, withreference to the attached drawing showing a non-restrictive embodimentof it.

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the attached drawing:

[0024]FIG. 1 is a perspective view showing one step of the process forproducing decorations on an object through machining according to theinvention.

[0025]FIG. 2 is a perspective view of a portion of an object produced bymeans of the process according to the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] When referring to FIG. 1, one can see a complex 1 produced byassembling bars 2 with a square cross-section, made integral with eachother through appropriate means, for example through a gluing operation.

[0027] In this embodiment, the bars 2 are of two different shades andare arranged alternately, so as to form lines in the longitudinaldirection and a check in cross-section. Of course, many arrangements arepossible, by modifying the shades and/or the colors of the bars 2, bymodifying the shapes of the bars 2, and through the arrangement of thelatter in the complex 1.

[0028] When referring now to FIG. 2, one can see a portion of an object3 produced through turning a complex 1 made through arranging identicalbars with a square cross-section, but of different shades.

[0029] It can be seen that, according to the machining depth, differentpatterns are achieved. Moreover, turning allows producing, in additionto the rounded shapes that are achieved in a well-known way, symmetricaldecorations that have harmonious roundnesses.

[0030] It will be understood that, through a different arrangement ofthe bars 2, i.e. for example a non-symmetric arrangement, it is possibleto create patterns with original shapes.

[0031] The process according to the invention is aimed at producingnumerous objects in the field of furniture, such as, in anon-restrictive way, table and chair feet, lamp stands, etc.

[0032] The process according to the invention advantageously allowsproducing original parts that are different from any other, simply bychanging the location of the bars 2 within the complex 1, and/or bychanging the machining, whether in shape or in depth.
